Application filed August 13, 1921. Serial No. 492,044.

To all whom it may concern:

Be it known that 1, CHARLES H. TURNER, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented a new and useful Car Ventilator, of whichthe following is a specification.

This invention relates to a ventilator particularly designed for use inthe upper part of a railway passenger car. Much difficulty has beenencountered in securing proper ventilation of such cars when in motion,as strong direct currents of air are objectionable and the exclusion ofdriving rain or sleet is an absolute necessity.

It is the object of my invention to provide a car ventilator whichcombines simplicity of construction with reliable and satisfactoryoperation. With this general object in view, my invention relates moreparticularly to arrangements and combinations of parts which will behereinafter described and more particularly pointed out in the appendedclaims.

Two slightly different forms of my invention are shown in the drawingsin which Fig. 1 is a sectional elevation of my improved ventilator asapplied to a car roof;

Fig. 2 is a partial plan view of the ventilator shown in Fig. 1;

Fig. 3 is a detail sectional view taken along the line 33 in Fig. 1;

Fig. 4 is a partial bottom view of the damper or air regulator shown inFig. 1;

Fig. 5 is a sectional elevation of a slightly modifiied form of myimproved ventilator, applied to a car of the monitor type, and

Fig. 6 is a side elevation of the ventilator shown in Fig. 5.

Referring to Figures 1 to 4, I have shown a ventilator of asubstantially rectangular form, including an end 10, a grid-like outerportion 11, and an imperforate portion 12 forming the opposite end, anda portion of the outer side of the ventilator. A baffle plate 13 isfixed within the ventilator and is provided with a shoulder 14 near oneend.

The baflie plate is inclined toward the outer surface of the ventilatorand the end of the plate is out-turned at 15 for a purpose to bedescribed. The battle plate 13 is soldered or otherwise secured to theside walls 16 of the ventilator and the lower end is extended to formwith the outwardly flanged portions of the sides 16 and end 12 an openframe work around the ventilator opening 17 in the roof 18. The baffleplate is stiffened by the provision of angle iron members 19, Fig. 3,extending from the shoulder 14 to the out-turned end 15. The lower edgeof the casing 10 is out-turned as shown in Fig. 1 to provide a drainageopening 20 adjacent to the shoulder 14. v

The lower side of the opening 17 in the roof 18 is covered by a plate orframe 22 having openings 23 therein adapted tobe covered by a slidingplate or damper 24 having corresponding openings 25 and provided with ahandle 26. by which it may be moved.

Having described the construction of this form of my improvedventilator,the advantages derived from the use thereof will be readilyapparent. It is found that the passage of air across a gridd'ikesurface, such as the surface 11, tends to create suction in the grid,withdrawing air through the ventilator from the interior of the car. Thepath of the air currents from the interior of the car around the battleplate 13 and out through the grid 11 is clearly indicated by arrows inFig. 1.

Rain or sleet entering through the grid 11 will be received by thebafiFle plate 13 and will drain out through the opening 20 without thepossibility of entering the car through the roof opening 17. Theoutturned end 15 of the plate 13 aids materially in protecting theinterior of the car from moisture, and the shoulder 14 serves a similarpurpose. The car ventilation may, of course, be easily regulated bysuitably positioning the sliding damper plate 24.

In Figs. 5 and 6, I have shown a ventilator of very similar constructionapplied to a car of the monitor type.

This ventilator includes a grid 30, a bafiie plate 31 having anout-turned portion 32, and a continuous curved imperforate end and outerside portion 33, all of these parts being in a general way similar tothe corresponding parts of the ventilator shown in Figs. 1 to 4. A. sashor window 34 may be provided in place of the slide previouslydescribbed, the sash being pivoted to swing to open or closed positionin the usual way.

The grid 30, being at the lowest part of th ventilator, acts also toprovide drainage and renders'the special drainage opening unnecessary.The baffle plate 31 is therefore continued to; the bottom of theventilator ivhereit issecured to the slightly inclined bottoin plate Thepathiof the air currentsuis indicated by'the arrows and does not differmaterially from-the circulation in the form previously described;

Having thus described tWo forms of my invention, it Wlll be evidentthatv changes;

and modifications can be made therein by those skilled in the artWithin-thespirit and scope of my invention as set forth in theCll'l-IDSHHQl I do not Wisln-to-lee-otherwise limited to theClQtEtl-lSllQlQlll disclosediibut What I clai1nisz-- l.
